NUT-LOCK.

Specification of Letters Patent. I

Application filed Augnst i, 1906. Serial No. 329,181.

To all whmn it Wmy concern.-

Be it known that 1, JOHN W. KREITZBURG, a citizen of the United States, residing at Allegany, in the county of Allegany and State of Maryland, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to nut-locks; and one of the objects of the same is to provide means for locking two nuts upon the ends of bolts passing through the web of a rail and through a fish-plate and providing means for quickly adjusting the nuts upon the bolts and holding them in adjusted positions.

Another object of my invention is to provide a simple and reliable device for locking nuts upon bolts and to permit the nuts to be adjusted from time to time upon the bolts to quickly move the locking device in position to hold the nut from turning.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a face view of a nut-lock made in accordance with my invention and showing the nut-lock secured to a plate. Fig. 2 is an edge view of the-same. Fig. 3 is a vertical section of the same. Fig. 4 is a front elevation of a modified form of my invention secured to the meeting ends of two railway-rails. Fig. 5 is a vertical sectional view taken through Fig. 4.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the body portion of the nut-lock, comprising a plate having a pair of oppositely-extending spring-tongues 2 cut therefrom and sliding stops 3 mounted to move upon the body portion 1, said stops 3 each having a guideway 4 upon its rear portion through which the spring-tongues 2 may be adjusted to permit the stops 3 to slide inward toward each other away from the surface of the nut 5 when it is required to adjust said nuts upon the bolts 6. After the nuts 5 have been properly tightened upon the bolts the stops 3 may be moved outward against the side surface of the nut, and the spring-tongues 2 will extend away from the plane of the body portion 1 of the plate and bear against the inner surfaces of the stops 3, thus preventing the nuts 5 from turning upon the bolt 6.

As shown in Figs. 4 and 5, the springtongue at is riveted at b to a fish-plate c, and the oppositely-projecting ends (Z of said tongue have a tendency to spring outward from the fish-plate c to hold the sliding stops e against the sides of the nuts 5. The stops 6 are each provided with lips f, which extend into a groove or space between the upper edge of the fish-plate c and the under surface of the rail-tread, as shown more clearly in Fig. 5. When it is desired to adjust the nuts upon the bolts, the tongues 2 or d are pressed downward and the stops 3 or e are pushed inward toward each other to permit 1 the nuts to turn upon the bolts. have been properly adjusted, the stops are pushed outward 'until the outer terminal ends of the spring-tongues spring away from the body portion of the plate to bear against When they 5 the inner sides of the stops and hold the nuts from turning, as will be understood. The slides 3 move in a recess in the fish-plate through which the bolts pass.

From the foregoing it will be seen that a nut-lock constructed in accordance with my invention will readily permit the adjustment of the nut upon the bolt and be quickly moved to a position to hold the nuts when adjusted.

Having thus described the invention, what is claimed as new is 1. A nut-lock comprising a plate, oppositely-projecting spring-tongues on said plate and normally springing away from said plate at their ends, in combination with stops mounted to slide over the tongues on the plate, said stops being held up against the sides of the nuts by the terminal ends of said spring-tongues, substantially as described.

2. A nut-lock comprising a plate having oppositely-disposed spring-tongues, the ends of which are normally sprung away from the plane of the plate, stops mounted to slide over the tongues, and bear against the side edges of the nuts when said spring-tongues are sprung outward to hold the stops from sliding, said tongues bearing at their outer ends against said stops when in locking position, substantially as described.

In testimony whereof I afliX my signature in presence of two Witnesses.
